Therefore, the drilling pipe feeder 100 according to the present invention can improve the efficiency of the drilling operation by reducing the time required for the drilling operation.

Hereinafter, the mounting part 130, the insertion hole 140, and the rotation part 150 will be described in detail with reference to the accompanying drawings.

Referring to FIGS. 2 to 4, the mounting portion 130 is rotatably coupled to the drill rig 110. A plurality of the drill pipes 120 may be mounted on the mounting portion 120. For example, a first drilling pipe 121 (shown in Fig. 6) and a second drilling pipe 122 (shown in Fig. 6) may be mounted on the mounting portion 130, The mounting portion 120 may be rotated in a state where the drill pipe 130 is mounted, thereby positioning the drill pipe 130 in the supply position P1. The mounting portion 130 may be rotated by the rotation portion 150 to sequentially position the drill pipe 120 at the supply position P1. The mounting part 130 may be formed in a cylindrical shape but is not limited thereto and a plurality of the drilling pipes 120 may be mounted and the drilling pipes 120 may be sequentially positioned at the supplying position P1. But it may be formed in other forms as long as it can be rotated.

The rotation unit 150 may be installed in the derrick 111a. The rotating part 150 can sequentially position the drilling pipes 12 at the supply position by rotating the mounting part 130 about the rotation axis. Although not shown, the rotation unit 150 may include a motor that provides a rotational force. The motor may be directly coupled to the rotation shaft of the mounting portion 130 to rotate the mounting portion 130.

 Therefore, the drilling pipe supply apparatus 100 according to the present invention can move the second drilling pipe 122 to be coupled with the first drilling pipe 121 from the loading site to the drilling unit 111 side Can be omitted. Accordingly, the drilling pipe supply apparatus 100 according to the present invention can reduce the time required for transferring the drilling pipe 120 from the loading station in the drilling operation. Accordingly, the drilling pipe feeder 100 according to the present invention can improve the efficiency of the drilling operation by reducing the time required for the drilling operation.

The rotation unit 150 may be arranged such that any one of the insertion holes 140 is sequentially positioned at the replenishing position P2 for inserting the drill pipe 120 into the insertion hole 140 do. For this, the rotation unit 150 may rotate the mounting unit 130 clockwise or counterclockwise. As the rotary part 150 rotates the mounting part 130, the drill pipe 120 is supplied at the supply position P1 and then the other drill pipe 120 Can be positioned at the feeding position P1.

Accordingly, the drilling pipe feeder 100 according to the present invention can further contribute to improving the efficiency of the drilling operation.

Here, the insertion holes 140 are formed to have the same distance about the rotation axis of the mounting portion 130. For example, when the mounting portion 130 is formed in a circular shape, the insertion holes 140 may be formed to have the same distance along the circumference of the mounting portion 130 about the rotation axis of the mounting portion 130.

As compared with the case where the insertion holes 150 are formed to have different distances with respect to the rotation axis of the mounting portion 130, the drill pipe supply device 100 according to the present invention, The drilling pipe 120 can be transferred to the drilling unit 111 side without correcting the position. Therefore, the drill pipe supply apparatus 100 according to the present invention can omit the operation for correcting the positions of the insertion holes 140. [ Accordingly, the drilling pipe supply apparatus 100 according to the present invention can further contribute to reducing the time required for the drilling operation.

The drill pipe feeder 100 according to the present invention may include a fixing portion 160 for supporting the mounting portion 130.

The fixing portion 160 is coupled to the drilling unit 111. The fixing part 160 fixes the drill pipe 120 to the supply position P1. The fixing part 160 may be coupled to the mounting part 130 through the rotation part 150. In this case, one end of the rotation unit 150 may be fixed to the fixing unit 160, and the other end thereof may be coupled to the rotation axis of the mounting unit 130. The fixing unit 160 may be configured to supply the drilling pipe 120 to the drilling unit 111 only at the supply position P1.

Accordingly, the drill pipe supply apparatus 100 according to the present invention is implemented such that the drill pipe 120 is not arbitrarily released from the insertion hole 140. Therefore, in the drill pipe supply apparatus 100 according to the present invention, when the drill pipe 120 is detached from the mount 130, it is possible to reduce the occurrence of a safety accident such as stuck worker in the drill pipe 120 .

The fixing portion 160 may include a supply hole 161 for supplying the drilling pipe 120 to the drilling unit 111 side.

Accordingly, the drill pipe feeder 100 according to the present invention can prevent the drill pipe 120 from being supplied to the side of the door frame 111b at a position other than the feed position P1. Therefore, the drilling pipe supply apparatus 100 according to the present invention can accurately supply the drilling pipe 120 onto the drilling pipe 120 during the drilling operation. Accordingly, the drilling pipe supply apparatus 100 according to the present invention can reduce the time required for the operation of combining the drilling pipe 120 and the other drilling pipe 120 during the drilling operation.

FIG. 6 is a cross-sectional view for explaining a modified example of the drill pipe feeder according to the present invention, and FIGS. 7 to 9 are sectional views for explaining the first support portion, the second support portion, and the lift portion in the drill pipe according to the present invention.

The drill pipe supply apparatus 100 according to the present invention may include a lift unit 170 for lifting the drill pipe 120.

Referring to FIG. 6, the elevating part 170 inserts the drilling pipe 120 into the insertion hole 140. For this, the elevating unit 170 lifts the drilling pipe 120, which is loaded in a direction parallel to the direction of the drilling pipe 120 inserted into the insertion hole 140. For example, the elevating unit 170 can elevate the drilling pipe 120 to be conveyed through the conveying unit 180 installed on the drill rig. The elevation part 170 may be rotatably installed on the drill pipe so that the drill pipe 120 can be moved up and down.

Accordingly, the drill pipe supply apparatus 100 according to the present invention is capable of supplying the drill pipe 120, which is installed in a raised state, to the drill pipe 120 through the lift unit 170, as compared with the case where the drill pipe 120 is laid and transported The drill pipe 120 can be inserted into the insertion part 140, so that the step of raising the drill pipe 120 can be omitted. Therefore, the drilling pipe supply apparatus 100 according to the present invention can reduce the time required for the replenishment of the drilling pipe 120. Accordingly, the drilling pipe supply apparatus 100 according to the present invention can further reduce the delay time for supplying the drilling pipe 120, so that the efficiency of the drilling operation can be further improved.

The transfer unit 180 transfers the drilling pipe 120 to the elevating unit 170 in a direction parallel to the direction of the drilling pipe 120 inserted into the insertion hole 140.

7 to 9, the drill pipe supply apparatus 100 according to the present invention includes a first support portion 191 for supporting the first drill pipe 121 and a second support portion 191 for supporting the second drill pipe 122 And a second support portion 192.

Referring to FIG. 7, the first supporting part 191 is installed in the mounting part 130 to support the first drilling pipe 121. The first supporting part 191 presses the first drilling pipe 121 in a state where the first drilling pipe 121 is inserted into the insertion hole 140. Accordingly, the first supporting part 191 may fix the first drilling pipe 121 to the mounting part 130. Although not shown, the first support portions 191 may be installed at positions where the supply holes 140 are formed to support the drill pipes 120.

[ In this case, the first drilling pipe 121 may include a first support groove 1211 into which the first support portion 191 is inserted. For example, when the first drilling pipe 121 is inserted into the insertion hole 140, the first support portion 191 moves in the direction toward the first support groove 1211, 1211). The first support portion 191 may be moved away from the first support groove 1211 so that the first drilling pipe 121 may be detached from the insertion hole 130. [

The second supporting portion 192 is installed in the elevating portion 170 to support the second drilling pipe 122. The second support part 192 may be inserted into the second drilling pipe 122 to support the second drilling pipe 122. In this case, the second drilling pipe 122 may include a second support groove 1221 into which the second support portion 191 is inserted. For example, when the second drilling pipe 122 is transferred to the elevation part 170, the second support part 192 moves in the direction toward the second support groove 1221, 1221, respectively. When the second drilling pipe 122 is supplied from the transfer unit 180 to the elevating unit 170 or fixed to the mounting unit 130, The second drilling pipe 122 can be moved away from the elevating portion 170 by moving in the direction away from the elevating portion 1221. [

Accordingly, the drill pipe supply apparatus 100 according to the present invention can prevent the drilling pipe 120 from being arbitrarily disengaged from the mounting portion 130 or the elevating portion 170. [ Therefore, it is possible to prevent a safety accident from occurring due to the drill pipe 120 that has been detached from the drill pipe feeder 100 according to the present invention. Therefore, the drilling pipe feeder 100 according to the present invention can contribute to improve the stability of the drilling operation.

The second support portion 192 may prevent the drilling pipe 120 from being separated from the elevating portion 170 by pressing the drilling pipe 120 located at the elevating portion 170.

Here, the elevating unit 170 may rotate the second drilling pipe 122 to engage the first drilling pipe 121 and the second drilling pipe 122.

For example, when the first drilling pipe 121 is fixed to the mounting part 130, the elevating part 170 moves the first drilling pipe 121 and the second drilling pipe 122 to contact each other, The second drilling pipe 122 is moved up and down. In this state, the elevating part 170 can couple the first drilling pipe 121 and the second drilling pipe 122 by rotating the second drilling pipe 122.

The drill pipe supply apparatus 100 according to the present invention moves the drill pipe 120 coupled to the drill pipe 120 in the replenishing position P2 while the drill pipe 120 is coupled to the supply position P1 The time for supplying the drilling pipe 120 and the time for coupling the drilling pipe 120 can be reduced. Therefore, the drilling pipe feeder 100 according to the present invention can further contribute to reducing the time required for the drilling operation.

Although not shown, the elevating part 170, the first supporting part 191 and the second supporting part 192 may be driven by a plurality of driving units (not shown), respectively.

For example, the driving unit may supply the drilling pipe 130 to the mounting portion 130 by raising the elevating portion 170 while the drilling pipe 120 is mounted on the elevating portion 170 . Also, the driving unit can lower the elevating unit 170 to receive the drilling pipe 120 from the conveying unit 180.

The driving unit may move the first support portion 191 and the second support portion 192 away from the first support groove 1211 and the second support groove 1221 or may move away from the first support groove 1211 And the second support grooves 1221. [0086]
